inlinevirtual |
Provides the name of this algorithm.
The standard algorithm name can be a name like AES
or AES/GCM
. Some algorithms do not have standard names yet. For example, there is no standard algorithm name for Shoup's ECIES.
Reimplemented from Algorithm.

inlinevirtual |
Provides the digest size of the hash
Implements HashTransformation.
|
inline |
|
virtual |
Computes the hash of the current message.
digest | a pointer to the buffer to receive the hash |
digestSize | the size of the truncated digest, in bytes |
TruncatedFinal() calls Final() and then copies digestSize bytes to digest. The hash is restarted the hash for the next message.
COUNTOF(digest) <= DigestSize()
or COUNTOF(digest) <= HASH::DIGESTSIZE
ensures the output byte buffer is a valid size. Implements HashTransformation.

input | the additional input as a buffer |
length | the size of the buffer, in bytes |
